Abstract: According to one embodiment of the present invention, a method by which a terminal decodes a downlink control channel for a terminal configured so as to support a multi transmission time interval (TTI) length in a wireless communication system can comprise the steps of: receiving information on whether physical resource block (PRB) bundling occurs for a downlink control channel or on bundling size thereof; and decoding downlink control channels at a first TTI on the basis of the assumption that the same precoder has been applied to downlink control channels within the same PRB bundling, when the PRB bundling is configured for the downlink control channel.

Abstract: The present invention relates to a method for a terminal receiving an enhanced physical downlink control channel (EPDCCH) in a wireless access system supporting an unlicensed band, and the method may comprise the steps of: receiving, through an unlicensed-band cell (Ucell) configured in an unlicensed band, an EPDCCH comprising control information for scheduling the Ucell; and, on the basis of the control information, receiving downlink data from the Ucell. Here, if the EPDCCH is transmitted through a partial subframe (pSF), enhanced resource element groups (EREGs) constituting the EPDCCH are indexed from the start symbol of the pSF, and the pSF has a smaller size than one subframe, and the starting position of the pSF may not correspond to the subframe boundary of a primary cell (Pcell) configured in a licensed band.

Abstract: Provided are a method whereby user equipment (UE) receives downlink control information in a wireless communication system and UE using the method. The method comprises: receiving configuration information (MUCC-DCI configuration information) on multi-carrier downlink control information (MUCC-DCI) that may include pieces of scheduling information related to multiple serving cells; and performing blind decoding (BD) on the MUCC-DCI in a shared search space (shared SS) determined on the basis of the MUCC-DCI configuration information.

Abstract: Provided are a method for transmitting a vehicle-to-everything (V2X) signal performed by a user equipment (UE) having a limited transmission capability in a multi-carrier system and a UE using the method. The method includes selecting a first resource in a first carrier, if using a specific subframe in a second carrier exceeds a transmission capability of the UE considering the first resource, selecting a second resource randomly among the remaining subframes except the specific subframe in the second carrier and transmitting the V2X signal using the first resource and the second resource.
